Fig. 4

Cs3Sb (111) surface coated with monolayer MoS2. a Charge density difference with isovalue of 0.0015 e/bohr3, the yellow region corresponds to charge accumulation, and blue region corresponds to charge depletion, b planar averaged charge density difference, the arrow illustrates the induced dipole moment, c projected density of states of coated Cs3Sb, and d band alignments before and after MoS2 in contact with the surface. VB respresents valance bands, and CB conduction bands
